Fig. 6. Anemometer traces of wind generated by an attacking bat as it approaches a
mealworm target, captures it, and flies away. Since the anemometer was not
directly at the target's location, contact times (arrows) for each trace were
predicted based on the one trial when the anemometer was located at the target
(see Fig. 7). The examples
illustrate the major changes in the anemometer traces as peak velocities
increase; see text for details. The anemometer traces indicate that the bat
generates a short but strong stimulus as it approaches and captures the target
and a longer but weaker stimulus follows as the bat flies away. Scale bars: 50
cm s–1, 500 ms.
